Evaluation of role of doxycycline (a matrix metalloproteinase inhibitor) on renal functions in patients of diabetic nephropathy

This study was conducted to see the effect of doxycycline on renal functions, especially proteinuria, in patients of diabetic nephropathy (DN). The study included 40 clinically proven adult patients of DN. All patients were on stable doses of angiotensin-converting enzyme inhibitors (ACEIs) and or angiotensin receptor blockers (ARBs) for 2 months before the study. The patients were divided into two groups of 20 patients each. Group A patients were maintained on stable dose of ACEIs and/or ARBs, whereas Group B patients received doxycycline (100 mg/day) for a period of 3 months in addition to ACEIs and or ARBs. Adequate glycemic control was achieved with insulin or oral hypoglycemic agents in all the patients. Renal parameters were assessed at the beginning of the study, at 1, 3, and 6 months (after a washout period of 3 months). All renal parameters remained unaltered during the study in both groups. However, proteinuria showed improvement in Group B (doxcycycline group).The mean basal value of proteinuria was 1.74 + 1.70 for Group A and 2.17 + 2.95 for Group B. At the end of 3 months, proteinuria was 1.22 + 2.11 in Group B whereas it was 1.50 + 1.50 in Group A (p < 0.05). However, the decrease in proteinuria at 6 months in the two groups did not show any statistically significant difference. No significant side effects of doxycycline were observed. The study showed that doxycycline was effective in reducing proteinuria in patients of DN when used for the short duration of 3 months.

Bone mineral density in patients with predialysis chronic kidney disease.

Abstract Background: There is limited data available especially in Indian Population about prevalence of reduced bone mineral density (BMD) and various factors associated with it in CKD patients not on dialysis. Material: This study included 75 adult patients. Patients were divided into three groups depending upon GFR. Serum creatinine, albumin, calcium, phosphate (PO4), alkaline phosphatase, iPTH and Vitamin D were measured at baseline. BMD was measured by dual energy X-ray absorptiometry. Results: There were 51 male and 24 female patients. The mean serum phosphate, alkaline phosphatase and iPTH levels increased steadily as CKD progressed. On the other hand, mean corrected serum calcium and Vitamin D levels decreased progressively in group A, B and C. The mean serum PTH values in group A, B and C were 137.16 ± 109.85, 265.02 ± 132.03 and 328.14 ± 119.23 pg/mL, respectively and there was significant increase in mean PTH level from group A to group C (p < 0.05). The mean level of vitamin D showed a trend of declination from group A to C (p < 0.05). Z-score for group A, group B and group C was 1.11 ± 2.39, 0.87 ± 2.66 and −0.92 ± 1.59, respectively. Similarly, T score for the three groups were 0.47 ± 2.34, −0.4 ± 2.00 and −1.524 ± 1.42. Both T-score and Z-score positively correlated with GFR. There was negative correlation between Z-score and iPTH, and positive correlation with Vitamin D. Conclusion: Reduced bone density was seen early in the course of CKD as estimated from reduced BMD levels, increased prevalence of osteoporosis and increased fracture risk and it worsened with the progression of CKD.

Lipoprotein-A and carotid intima media thickness as cardiovascular risk factors in patients of chronic kidney disease

Patients in all stages of chronic kidney disease (CKD) are considered in the “high-risk group” for development of cardiovascular disease (CVD). The study was undertaken in 60 adult patients of chronic renal failure. The patients were divided into three groups: Group I had subjects with CKD (stages 1 and 2); Group II had subjects with CKD (stages 3 and 4) on conservative therapy for 3 months; and Group III had subjects with CKD (stage 5) on regular hemodialysis for at least 3–4 weeks. Carotid sonography was done in all patients at the time of inclusion in the study. The patients in all the groups were then followed for 6 months and the relevant investigations were carried out, initially at the time of presentation, and then at third- and sixth-month interval. The patients were monitored for various renal parameters along with serum lipoprotein-A [Lp (A)]. The value of carotid intima media thickness (CA-IMT) was increased in group II and III as compared to group I. The calcification of carotids was higher in patients of group III. The maximum number of patients having plaques and stenosis in the carotids were seen in group III (50%), followed by group II (20%). Patients in group III had 5–10 times higher levels of Lp (A) as compared to patients in group I. The comparison of Lp (A) levels between group I and group II was also highly statistically significant.

Evaluation of spectrum of peripheral neuropathy in predialysis patients with chronic kidney disease.

Abstract Introduction: Neurological complications secondary to the uremic state, contribute largely to the morbidity and mortality in patients with renal failure. The prevalence of peripheral neuropathy remains high in advanced renal dysfunction. Materials and methods: The present cross-sectional study was conducted on 100 adult patients of chronic kidney disease between 18 and 75 years of age with serum creatinine greater than 2 mg/dL. Apart from routine examination and baseline investigations, detailed history was elicited pertaining to patients’ neurological symptoms, and scored according to the Neurological Symptom Score. Motor nerve conduction velocity was measured from right median, ulnar, peroneal, and tibial nerves. Results: It was observed that neurological symptoms increased steadily with raise in serum creatinine. The mean nerve conduction velocities (NCVs) of right median nerve, ulnar nerve, peroneal nerve, and tibial nerve were 51.34 ± 6.07, 53.04 ± 5.91, 44.72 ± 6.14, and 44.20 ± 5.17, respectively. The NCVs of all the tested nerves decreased significantly with increase in serum creatinine levels (p < 0.01): 70% of the patients had uremic polyneuropathy; 6% had asymptomatic neuropathy, 51% had symptomatic non-disabling neuropathy, while disabling neuropathy was seen in 13% of the patients. Conclusion: Our data suggests that NCV testing when complimented with meticulous neurological assessment can provide invaluable input. These tests apart from helping us detect neuropathy in advanced renal dysfunction; can also detect the disease in largely asymptomatic patients which avoids the necessity to order for detailed neurophysiological investigation

Disseminated tuberculosis causing isolated splenic vein thrombosis and multiple splenic abscesses

Tuberculosis is a common infectious cause of splenic enlargement in developing countries, but tubercular splenic abscesses are a rare presentation, found predominantly in immunocompromised populations. We report a case of tubercular splenic abscesses with isolated splenic vein thrombosis in an immunocompetent person.

Systemic lupus erythematosus presenting as fulminant lupus pneumonitis: a rare case report

We report a case of 19 year-old female patient diagnosed as systemic lupus erythematosus (SLE) presented with fever and diffuse cutaneous lesions. During the hospital stay she had acute pneumonia, pleural effusion and respiratory failure, which required intensive care unit (ICU) care and mechanical ventilator support. A fulminant course of the disease, decreased values of complement levels and positive antinuclear antibodies (ANA) in pleural fluid and repeated negative sputum for acid-fast bacillus, blood cultures enabled diagnosis of fulminant lupus pneumonitis. Fulminant lupus pneumonitis is a rare but potentially life threatening complication of SLE. Management requires involvement of multiple specialties and rigorous efforts in reviving the patient.

Senior-loken syndrome with rare manifestations: a case report.

Senior-Loken syndrome refers to a disorder in which there is a combination of nephronophthisis and retinal dystrophy. The earliest presenting signs of the renal component are polyuria and polydipsia secondary to defective urinary concentrating ability. Nephronophthisis progresses to end-stage renal disease during the second decade. The retinal lesions are variable, ranging from severe infantile onset retinal dystrophy to more typical retinitis pigmentosa. There is a spectrum of other associated features, including skeletal, dermatological and cerebellar anomalies, observed in this entity. Here, we report a case of Senior-Loken syndrome associated with small hand (short metacarpals) and madarosis. To date, there are no cases reported in the literature describing the association of madarosis with this syndrome, and the presence of small hands has been reported only once.

Multiple splenic infarcts in acute Plasmodium vivax malaria: A rare case report

In tropical countries like India, malaria has been one of the most common parasitic illnesses leading to frequent hospitalization and causing major economic burden among the masses. Although Plasmodium vivax infection is considered to be benign, in contrast to Plasmodium falciparum infection which is notorious for its severe splenic complications can occur frequently. Splenomegaly tends not to receive special attention, as it is not usually accompanied by any symptoms and can be gradually resolved via standard antimalarial therapy. Splenic infarction, although rarely attributable to malaria in an endemic region with high parasitemia, can be a rare presentation of this disease entity.

Nephrocalcinosis: a rare presenting manifestation of primary Sjögren’s syndrome

Renal involvement in primary Sjögren’s syndrome (pSS) is not uncommon. Autoimmune tubulointerstitial disorders and distal renal tubular acidosis (dRTA) account for majority of the cases of renal involvement. While dRTA may precede the onset of sicca syndrome in pSS, nephrocalcinosis as a presenting manifestation of pSS is rare. Here, to emphasize the need for initiating investigations for pSS in any patient presenting with nephrocalcinosis due to dRTA, we report a 21-year-old woman presenting with nephrocalcinosis long before pSS was objectively diagnosed.

Anti-dsDNA negative and anti-Ro positive lupus nephritis: a report of a rare case

Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease, characterized by an autoantibody response to various nuclear and cytoplasmic antigens. Renal disease in SLE occurs in 40-75% of patients, most often within five years of onset of disease, and is one of the strongest predictors of a poor outcome. A hallmark of glomerular involvement in lupus nephritis is the presence of autoantibodies against double-stranded DNA (dsDNA). Its level usually correlates with disease activity. Our patient presented with a rash resembling malar rash and features of nephrotic syndrome. On investigating, patient was found to have pancytopenia, raised erythrocyte sedimentation rate and depressed serum C3 levels with positivity of antinuclear antibodies and anti- Ro antibodies. However, most of the markers of lupus nephritis including anti dsDNA antibody were negative. Renal biopsy showed features of lupus nephritis (class-IV). Differential item functioning studies showed a full house immunoflourescence staining pattern characteristic of lupus nephritis. Association of Anti-Ro antibody alone with lupus nephritis is less known in literature. Negativity of anti-dsDNA antibody, which is usually considered to be diagnostic of lupus nephritis, poses a diagnostic dilemma short of renal biopsy. Till date only very few cases of non-drug induced lupus nephritis with negative dsDNA antibodies have been reported. In this report we wish to highlight a case of lupus nephritis which was negative for its specific anti dsDNA antibodies and with possible role of anti-Ro antibodies in the pathogenesis of lupus nephritis although the underlying mechanism is incompletely understood.
