Safety and outcome of treatment of metastatic melanoma using 3-bromopyruvate: a concise literature review and case study

3-Bromopyruvate (3BP) is a new, promising anticancer alkylating agent with several notable functions. In addition to inhibiting key glycolysis enzymes including hexokinase II and lactate dehydrogenase (LDH), 3BP also selectively inhibits mitochondrial oxidative phosphorylation, angiogenesis, and energy production in cancer cells. Moreover, 3BP induces hydrogen peroxide generation in cancer cells (oxidative stress effect) and competes with the LDH substrates pyruvate and lactate. There is only one published human clinical study showing that 3BP was effective in treating fibrolamellar hepatocellular carcinoma. LDH is a good measure for tumor evaluation and predicts the outcome of treatment better than the presence of a residual tumor mass. According to the Warburg effect, LDH is responsible for lactate synthesis, which facilitates cancer cell survival, progression, aggressiveness, metastasis, and angiogenesis. Lactate produced through LDH activity fuels aerobic cell populations inside tumors via metabolic symbiosis. In melanoma, the most deadly skin cancer, 3BP induced necrotic cell death in sensitive cells, whereas high glutathione (GSH) content made other melanoma cells resistant to 3BP. Concurrent use of a GSH depletor with 3BP killed resistant melanoma cells. Survival of melanoma patients was inversely associated with high serum LDH levels, which was reported to be highly predictive of melanoma treatment in randomized clinical trials. Here, we report a 28-year-old man presented with stage IV metastatic melanoma affecting the back, left pleura, and lung. The disease caused total destruction of the left lung and a high serum LDH level (4,283 U/L). After ethics committee approval and written patient consent, the patient received 3BP intravenous infusions (1-2.2 mg/kg), but the anticancer effect was minimal as indicated by a high serum LDH level. This may have been due to high tumor GSH content. On combining oral paracetamol, which depletes tumor GSH, with 3BP treatment, serum LDH level dropped maximally. Although a slow intravenous infusion of 3BP appeared to have minimal cytotoxicity, its anticancer efficacy via this delivery method was low. This was possibly due to high tumor GSH content, which was increased after concurrent use of the GSH depletor paracetamol. If the anticancer effectiveness of 3BP is less than expected, the combination with paracetamol may be needed to sensitize cancer cells to 3BP-induced effects.

Warburg effect increases steady-state ROS condition in cancer cells through decreasing their antioxidant capacities (Anticancer effects of 3-bromopyruvate through antagonizing Warburg effect)

Cancer cells undergo an increased steady-state ROS condition compared to normal cells. Among the major metabolic differences between cancer cells and normal cells is the dependence of cancer cells on glycolysis as a major source of energy even in the presence of oxygen (Warburg effect). In Warburg effect, glucose is catabolized to lactate that is extruded through monocarboxylate transporters to the microenvironment of cancer cells, while in normal cells, glucose is metabolized into pyruvate that is not extruded. Pyruvate is a potent antioxidant, while lactate has no antioxidant effect. Pyruvate in normal cells may be further metabolized to acetyl CoA and then through Krebs cycle with production of antioxidant intermediates e.g. citrate, malate and oxaloacetate together with the reducing equivalents (NADH.H+). Through activity of mitochondrial transhydrogenase, NADH.H+ replenishes NADPH.H+, coenzyme of glutathione reductase which replenishes reduced form of glutathione (potent antioxidant). This enhances antioxidant capacities of normal cells, while cancer cells exhibiting Warburg effect may be deprived of all that antioxidant capabilities due to loss of extruded lactate (substrate for Krebs cycle). Although intrinsic oxidative stress in cancer cells is high, it may be prevented from reaching progressively increasing levels that are cytotoxic to cancer cells. This may be due to some antioxidant effects exerted by hexokinase II (HK II) and NADPH.H+ produced through HMP shunt. Glycolytic phenotype in cancer cells maintains a high non-toxic oxidative stress in cancer cells and may be responsible for their malignant behavior. Through HK II, glycolysis fuels the energetic arm of malignancy, the mitotic arm of malignancy (DNA synthesis through HMP shunt pathway) and the metastatic arm of malignancy (hyaluronan synthesis through uronic acid pathway) in addition to the role of phosphohexose isomerase (autocrine motility factor). All those critical three arms start with the substrate G6P that is a direct product of HK II. 3-bromopyruvate (3BP, inhibitor of HK II) may prove as a promising anticancer and antimetastatic agent based on antagonizing the Warburg effect and disturbing the malignant behavior in cancer cells.

Percutaneous excretion of iron and ferritin (through Al-hijamah) as a novel treatment for iron overload in beta-thalassemia major, hemochromatosis and sideroblastic anemia

Iron overload is a big challenge when treating thalassemia (TM), hemochromatosis and sideroblastic anemia. It persists even after cure of TM with bone marrow transplantation. Iron overload results from increased iron absorption and repeated blood transfusions causing increased iron in plasma and interstitial fluids. Iron deposition in tissues e.g. heart, liver, endocrine glands and others leads to tissue damage and organ dysfunction. Iron chelation therapy and phlebotomy for iron overload have treatment difficulties, side effects and contraindications. As mean iron level in skin of TM patients increases by more than 200%, percutaneous iron excretion may be beneficial. Wet cupping therapy (WCT) is a simple, safe and economic treatment. WCT is a familiar treatment modality in some European countries and in Chinese hospitals in treating different diseases. WCT was reported to clear both blood plasma and interstitial spaces from causative pathological substances (CPS). Standard WCT method is Al-hijamah (cupping, puncturing and cupping, CPC) method of WCT that was reported to clear blood and interstitial fluids better than the traditional WCT (puncturing and cupping method, PC method of WCT). In other word, traditional WCT may be described as scarification and suction method (double S technique), while Al-hijamah may be described as suction, scarification and suction method (triple S technique). Al-hijamah is a more comprehensive treatment modality that includes all steps and therapeutic benefits of traditional dry cupping therapy and WCT altogether according to the evidence-based Taibah mechanism (Taibah theory). During the first cupping step of Al-hijamah, a fluid mixture is collected inside skin uplifting due to the effect of negative pressure inside sucking cups. This fluid mixture contains collected interstitial fluids with CPS (iron, ferritin and hemolyzed RBCs in thalassemia), filtered fluids (from blood capillaries) with iron and hemolyzed blood cells (hemolyzed RBCs, WBCs and platelets). That fluid mixture does not contain intact blood cells (having diameters in microns) that are too big to pass through pores of skin capillaries (6-12nm in diameter) and cannot be filtered. Puncturing skin upliftings and applying second cupping step excrete collected fluids. Skin scarifications (shartat mihjam in Arabic) should be small, superficial (0.1mm in depth), short (1-2mm in length), multiple, evenly distributed and confined to skin upliftings. Sucking pressure inside cups (-150 to -420mmHg) applied to skin is transmitted to around skin capillaries to be added to capillary hydrostatic pressure (-33mmHg at arterial end of capillaries and -13mmHg at venous end of capillaries) against capillary osmotic pressure (+20mmHg). This creates a pressure gradient and a traction force across skin and capillaries and increases filtration at arterial end of capillaries at net pressure of -163 to -433mmHg and at venous end of capillaries at net pressure of -143 to -413mmHg resulting in clearance of blood from CPS (iron, ferritin and hemolyzed blood cells). Net filtration pressure at renal glomeruli is 10mmHg i.e. Al-hijamah exerts a more pressure-dependent filtration than renal glomeruli. Al-hijamah may benefit patients through inducing negative iron balance. Interestingly, Al-hijamah was reported to decrease serum ferritin significantly (by about 22%) in healthy subjects while excessive traditional WCT was reported to cause iron deficiency anemia. Al-hijamah is a highly recommended treatment in prophetic medicine. In conclusion, Al-hijamah may be a promising adjuvant treatment for iron overload in TM, hemochromatosis and sideroblastic anemia.

Anatomical Sites for Practicing Wet Cupping Therapy (Al-Hijamah): In Light of Modern Medicine and Prophetic Medicine

Wet cupping therapy (WCT) is increasingly practiced worldwide, especially in hospitals of China and Germany. Al-hijamah is WCT of prophetic medicine. Al-hijamah was recently reported to do better than Chinese WCT. Alhijamah filters and clears blood and interstitial fluids from causative pathological substances (CPS) including disease-causing substances (DCS) and disease-related substances (DRS) according to the evidence-based Taibah theory. This occurs via a percutaneous pressure-dependent and size-dependent filtration of capillary blood of skin circulation. This explains why Al-hijamah treats diseases with different pathogeneses e.g. headache and rheumatoid arthritis. Hijamatology is a novel term describing the science of education, qualification, practice and research related to Al-hijamah. Al-hijamah was described by Prophet Mohammad (Muhammad) peace be upon him as one of the best remedies: “The best among what you use in therapy is Al-hijamah”. No published report is there to guide researchers, physicians and practitioners to the best anatomical sites for practicing Al-hijamah for treating different diseases as this science is still in its beginning and may benefit from future research. Based on our background in prophetic medicine, anatomy, medicine and our practice, we review here prophetic medicine remedies, indications and anatomical sites that may be suitable for practicing Al-hijamah. Suitable anatomical sites for practicing Alhijamah differ from disease to disease. In prophetic medicine, Al-hijamah was practiced at skin overlying and near sites of pathology e.g. skin overlying skull vertex, dorsal surface of the foot, thigh region and at general sites e.g. kahel region (mainly skin overlying 7th cervical vertebra) and akhdayin (both sides of the neck posterior to ears). We report here a novel technique (Salah’s technique) for practicing Al-hijamah safely at some special anatomical sites. In conclusion, Al-hijamah is better to be practiced at sites of pathology (for local clearance), at back region and back of neck (for general blood clearance).

Al-hijamah and oral honey for treating thalassemia, conditions of iron overload, and hyperferremia: toward improving the therapeutic outcomes.

Iron overload causes iron deposition and accumulation in the liver, heart, skin, and other tissues resulting in serious tissue damages. Significant blood clearance from iron and ferritin using wet cupping therapy (WCT) has been reported. WCT is an excretory form of treatment that needs more research efforts. WCT is an available, safe, simple, economic, and time-saving outpatient modality of treatment that has no serious side effects. There are no serious limitations or precautions to discontinue WCT. Interestingly, WCT has solid scientific and medical bases (Taibah mechanism) that explain its effectiveness in treating many disease conditions differing in etiology and pathogenesis. WCT utilizes an excretory physiological principle (pressure-dependent excretion) that resembles excretion through renal glomerular filtration and abscess evacuation. WCT exhibits a percutaneous excretory function that clears blood (through fenestrated skin capillaries) and interstitial fluids from pathological substances without adding a metabolic or detoxification burden on the liver and the kidneys. Interestingly, WCT was reported to decrease serum ferritin (circulating iron stores) significantly by about 22.25% in healthy subjects (in one session) and to decrease serum iron significantly to the level of causing iron deficiency (in multiple sessions). WCT was reported to clear blood significantly of triglycerides, low-density lipoprotein (LDL) cholesterol, total cholesterol, uric acid, inflammatory mediators, and immunoglobulin antibodies (rheumatoid factor). Moreover, WCT was reported to enhance the natural immunity, potentiate pharmacological treatments, and to treat many different disease conditions. There are two distinct methods of WCT: traditional WCT and Al-hijamah (WCT of prophetic medicine). Both start and end with skin sterilization. In traditional WCT, there are two steps, skin scarification followed by suction using plastic cups (double S technique); Al-hijamah is a three-step procedure that includes skin suction using cups, scarification (shartat mihjam in Arabic), and second skin suction (triple S technique). Al-hijamah is a more comprehensive technique and does better than traditional WCT, as Al-hijamah includes two pressure-dependent filtration steps versus one step in traditional WCT. Whenever blood plasma is to be cleared of an excess pathological substance, Al-hijamah is indicated. We will discuss here some reported hematological and therapeutic benefits of Al-hijamah, its medical bases, methodologies, precautions, side effects, contraindications, quantitative evaluation, malpractice, combination with oral honey treatment, and to what extent it may be helpful when treating thalassemia and other conditions of iron overload and hyperferremia.

Updates in diagnosis and management of Ebola hemorrhagic fever

Ebola hemorrhagic fever is a lethal viral disease transmitted by contact with infected people and animals. Ebola infection represents a worldwide health threat causing enormous mortality rates and fatal epidemics. Major concern is pilgrimage seasons with possible transmission to Middle East populations. In this review, we aim to shed light on Ebola hemorrhagic fever as regard: virology, transmission, biology, pathogenesis, clinical picture, and complications to get the best results for prevention and management. We also aim to guide future research to new therapeutic perspectives to precise targets. Our methodology was to review the literature extensively to make an overall view of the biology of Ebola virus infection, its serious health effects and possible therapeutic benefits using currently available remedies and future perspectives. Key findings in Ebola patients are fever, hepatic impairment, hepatocellular necrosis, lymphopenia (for T-lymphocyte and natural killer cells) with lymphocyte apoptosis, hemorrhagic manifestations, and complications. Pathogenesis in Ebola infection includes oxidative stress, immune suppression of both cell-mediated and humoral immunities, hepatic and adrenal impairment and failure, hemorrhagic fever, activation of deleterious inflammatory pathways, for example, tumor necrosis factor-related apoptosis-inducing ligand, and factor of apoptotic signal death receptor pathways causing lymphocyte depletion. Several inflammatory mediators and cytokines are involved in pathogenesis, for example, interleukin-2, 6, 8, and 10 and others. In conclusion, Ebola hemorrhagic fever is a serious fatal viral infection that can be prevented using strict health measures and can be treated to some extent using some currently available remedies. Newer treatment lines, for example, prophetic medicine remedies as nigella sativa may be promising.
